Description by the Publisher
Detect IP addresses which are used as VPN anonymizer, open proxies, web proxies and Tor exits. The database includes records for all public IPv4 addresses.
Anonymous proxy servers are intermediate servers meant to hide the real identity or IP address of the requestor. Studies found that a large number of anonymous proxy users are generally responsible for online credit card fraud, forums and blogs spamming.
IP2Proxy database is based on a proprietary detection algorithm in parallel with evaluation of anonymous open proxy servers which are actively in use. Then it generates an up-to-date list of anonymous proxy IP address in the download area every 24 hours. Web developers can automate the download process once a day from our server and import the anonymous.
